including a channel part, and a rigid insert fitted within said
C-shaped channel part substantially filling the space provided
thereby, said insert constituting means for stiffening and
strengthening each sash.
2. The sliding window assembly of claim 1 wherein said lightweight
material is plastic.
3. The sliding window assembly of claim 1 and weatherstripping
means attached to said insert and extending outwardly of said
channel part for insulating said assembly from the weather
elements.
4. The sliding storm window assembly of claim 1 and magnetic means
carried by one of said first and second windows, means carried by
the other of said first and second window for mating with said
magnet means to insulate said assembly.
5. The sliding window assembly of claim 4 wherein said magnet means
includes biasing means connected to said one first and second
windows and extending towards the other window, a magnet connected
to said biasing means facing said other window, said mating means
including a metallic strip fastened to said other window, said
biasing means for accommodating movement of said magnet across said
metallic strip as said one window is slid into a closed
position.
6. The sliding window assembly of claim 1 wherein said channel part
is of an open sided configuration receiving said rigid insert.
Description
SUMMARY OF THE INVENTION
This invention relates to a door or window assembly and has special
but not limited application to a sliding glass storm door or
window.
The sliding door or window of this invention includes a sash formed
of lightweight non-metallic material such as rigid plastic. The
sash includes rigid inserts fitted in the vertical frame members to
strengthen the sash while maintaining its excellent insulative
properties. A magnetic strip weather seal can be provided between
the sash and its overlapped assembly components.
Accordingly, it is an object of this invention to provide for an
improved sliding glass door or window.
Another object of this invention is to provide for a lightweight
sliding glass storm door or window which is durable and strong.
Another object of this invention is to provide for a lightweight
sliding glass door or window which maintains excellent insulative
properties and is economical to produce and maintain.
Still another object of this invention is to provide a sliding
storm door or window assembly having magnetic weather
stripping.
Other objects of this invention will become apparent upon a reading
of the following description.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
The preferred embodiments herein described are not intended to be
exhaustive or to limit the invention to the precise forms
disclosed. They are chosen and described to explain the principles
of the invention and its application and practical use to thereby
enable others skilled in the art to utilize the invention.
FIGS. 1-3 depict a sliding glass door assembly 10 constructed
according to the principles of this invention. Assembly 10 includes
an outer rectangular frame 12 formed of a header 14, a threshold
18, and side members or jambs 20. Frame 12 is adapted to be fitted
into an accommodating wall opening. Header 14 and jambs 20 are each
generally U-shaped and include adjacent channel parts 22, 23.
Threshold 18 includes, as shown in FIG. 3, a channel part 24 which
accommodates movement of a sliding door 30, and an adjacent raised
channel part 28 which accommodates a normally stationary door
32.
Sliding door 30 includes an exterior frame or sash which includes
horizontal sash members 31 and 33 and vertical sash members 34 and
35. Lower sash member 33 is positioned in channel part 24 and is
adapted for sliding movement within the channel part. Channel part
24 may include an integral passageway 26 to catch dirt or other
impurities from door 30. A glazing panel 36 is secured between sash
members 31, 33-35 by being fitted into retainer channels 37 as
shown in FIGS. 2 and 3. Sash members 31, 33-35 are preferably
formed of lightweight generally thin-walled, shape-returning,
non-metallic material such as ABS plastic. Sash member 34 also
includes a rear opening C-shaped channel 38 into which a rigid
vertical insert 40 formed of a material such as rigid plastic or
metal is fitted. A weatherstrip element 42 of felt or the like is
carried by insert 40 and protrudes outwardly toward door 32 as seen
in FIG. 2. Sash member 34 further includes a vertically extending
lip 44 which protrudes outwardly toward door 32 and is turned in
the direction of sash member 35. Vertical sash member 35 includes a
front opening C-shaped channel 45 into which a rigid vertical
insert 46 of a material like insert 40 is inserted. Insert 46 is
handle-shaped and may be further secured to sash member 35 by
screws 48. Door horizontal sash members 31 and 33 of door 30
include felt weatherstrip elements 47 which contact channel part
22, 24. Vertical frame member 35 includes oppositely extending
weatherstrip elements 49.
Door 32 includes an exterior frame similar to door 30, having
horizontal sash members 50 and 41 and vertical sash members 52 and
53 formed of lightweight non-metallic material such as ABS plastic.
A glazing panel 55 is secured between sash members 50-53. Sash
member 52 also includes a front opening C-shaped channel 54 into
which a rigid vertical insert 56 formed of rigid plastic or metal
is fitted. A weatherstrip element 58 of felt or the like is carried
by insert 56 and contacts sliding door frame 30. Sash member 52
further includes a vertically extending lip 60 which protrudes
outwardly towards door 30 and is turned in the direction of sash
member 53 so as to overlap lip 44 of door 50 when the doors are
closed. Horizontal sash members 50, 51 include weatherstrip
elements 62, 64 which contact channel part 23, and vertical sash
member 53 includes oppositely-extending weatherstrip elements 66.
Sash member 53, due to its fixed position within supporting channel
23 of jamb 20, need no rigid insert for support.
FIG. 4 depicts an alternative type of weatherstrip element 68 which
includes a flexible bellows-like strip 70 secured in vertical
inserts 40, 56. A magnet overlay 74 is carried by strip 70. A
ferrous metallic strip 72 is secured to door sash members 35 and
52. As door 30 is closed, magnetic overlay 74 slides over strip 72
and adheres to the strip to form the weather seal. The flexible
strip 72 allows for good sealing contact with magnetic overlay
74.
FIGS. 5-7 depict a sliding glass window assembly 80 constructed
according to the principles of the invention. Window assembly 80
includes an outer rectangular frame 12' formed of a header 14' and
side members or jambs 20'. Frame 12' is adapted to be fitted into
an accommodating wall opening. All other parts of window assembly
80 are identical to the above-identified parts in door assembly 10,
and are identified in FIGS. 5-8 by identical numbers followed by a
' marking, as will not be described further in this
application.
It is understood that the above description does not limit the
invention to above-given details, but may be modified within the
scope of the appended claims. One such modification would be a
fixed, non-sliding window assembly.
